Answer:
y= 2x+5
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Parallel lines have the same gradient. Hence m=2.
Subst. m=2 into the equation:
y=2x +c
Now substitute a coordinate.
When x= -2, y=1,
1= 2(-2) +c
1= -4 +c
c= 1 +4
c=5
Thus, the equation of the line is y= 2x +5.
Answer:
22.5
Step-by-step explanation:
Using PEMDAS, we know that for expressions such as this, we're supposed to multiply before we add. This means that it should look something like this: (3.3 x 2.5) + (5.7 x 2.5). When you solve the multiplication first, you get 8.25 + 14.25. Solve, and you get 22.5. This problem can be solved using any basic calculator, or scratch paper!
The equations will only have one solution because they have different slopes and also next time use desmos for those kinds of problems it’ll always help
Answer:
Fist off composite numbers are whole numbers. And they have at least 3 factors.
Step-by-step explanation:
For example the number 6.
1 X 6= 6
2 X 3= 6
3 X 2= 6
6 X 1=6
It has 4 factors. The factors are 1,2,3,6.
Hope this helped :)
